Daniel Radcliffe has been forced to reiterate he is "straight" - after his new new anti-homophobia advert reignited recurring rumours over his sexuality.The Harry Potter actor has long been hounded by rumours he is homosexual, but he recently told reporters he isn't fazed by the speculation and thinks it's "awesome" when people presume he's gay. Since he fronted an anti-homophobia ad in the U.S. last month (Feb10), the rumours have arisen again - and he has spoken out to set the record straight. Radcliffe tells MTV.com, "I'm not gay. If people want to say that, they can. I'm not. I'm straight. "My favourite thing I saw was a guy on the internet who said, 'Of course he's gay - he's got a gay face', which I thought was kind of an odd thing to say anyway. "A gay face? That's a very worrying thing, like they have sat at home with pictures of me next to other famous gay folks."
